Goolsky 10pcs EV-Peak GA102 Battery Capacity Indicator Charge Marker Record Sticker for Rechargeable Battery

I have lots of rechargeable batteries that I store in little plastic cases (that fit 4 batteries per case). Seemed like every time I went to use the batteries, they are discharged. Hoping these little slide indicators help with that.These stick-on indicators are nice and small. They are 0.9 inches wide x 0.4 inches high x 0.1 inches tall. They have an adhesive backing that I stuck to the battery case. Just got them, so not sure how long the adhesive will hold for, but if they start to flake off, I am sure it's nothing a little crazy glue cant fix.

Nice piece for my RC batteries.

Initially these were great, but they don’t hold up to date to day use they end up falling off.

Great product! Securely mounts to battery. Small enough to fit most 2s or larger batteries. Slide indicator to GREEN after changing and to RED after use. Easy way to not get to the field with discharged batteries.

These indicators are good to know if the battery is charged or discharged. They stick on the battery and you just slide the plastic piece to either the Red or Green position to know if the battery is charged or requires charging. Well worth the cost.

This item is extremely useful to keep track of which batteries are charged. I gave 4 stars instead of 5, because this doesn't fit on all batteries. I ended up putting it on the battery case.

I'm using them in my laundry room so we know which basket cubbies need to be washed. and on the machine to know if it's dirty, and just waiting for enough laundry to make a full load. they slide back and forth just fine, and they seem to stick pretty well.

I have over 20 batteries for cameras and lights. These are indispensable for knowing when it's time to recharge.
